TwinPhone vs Quo (OpenPhone) 2026: Per-Seat Plan or Pay-As-You-Go

Quo (formerly OpenPhone) gives each user a US or Canadian number in web, desktop and mobile apps, with calls and texts that the whole team can see. Its help centre is direct about coverage: it only offers US and Canadian numbers, local or toll-free.

On its pricing page (checked 10 November 2026) Quo lists three plans, priced per user per month: Starter at $15 billed annually or $19 monthly, Business at $23 annually or $33 monthly, and Scale at $35 annually or $47 monthly. Every plan includes one local or toll-free number per user, with additional numbers at $5/month each, unlimited calling and texting within the US and Canada under a fair usage policy, and free porting of an existing number. There is a 7-day trial.

Two costs sit outside the plan. Business texting in the US requires carrier registration through The Campaign Registry, which Quo lists at a $19.50 one-time fee plus $1.50 to $3 per month. And calls or texts to other countries are an add-on billed from credits at per-destination rates.

Quo is a strong product for what it is built to do: shared numbers, a team inbox, call routing and texting customers from a business line.

TwinPhone has no plan at all for calling. You sign up with an email or Google account (no card, no phone number), add credit from $10, and call ordinary phones in 145+ countries from the browser, or from the iOS and Android apps. Calls to US and Canadian numbers cost $0.02/min; every other destination shows its rate in the dialer before the call connects. Calls are billed in whole minutes, rounded up, and unused credit does not expire.

A number is optional. US and Canadian numbers start at $3.19/month each, up to three per account, and you can cancel any time. A rented number receives calls in the browser, billed at $0.02/min, and receives text messages from US and Canadian senders. It cannot send SMS: there is no send button in TwinPhone. Without a rented number, the people you call see a shared TwinPhone number.

TwinPhone does not do team inboxes, call queues, number porting or emergency calls (911 cannot be dialled).

Quo is priced per seat because it is a team product. You pay every month for each person, and in return everyone shares numbers, conversations and contacts, and can text customers.

TwinPhone is priced per minute because it is a personal calling tool. You pay for the minutes you use, plus the number if you keep one. It has no seats, no shared inbox and no outgoing texts.

That makes the choice fairly clean:

• If you need to text customers, or several people need to answer the same number, Quo does it and TwinPhone does not.
• If you need to port an existing business number, Quo includes it; TwinPhone does not port numbers.
• If you mostly need a US or Canadian number to receive calls and verification texts, plus calls abroad, and you would rather not pay a monthly seat, TwinPhone costs less.

Quo (pricing page, 10 November 2026):

• Starter: $15/user/mo billed annually ($180/year), or $19 billed monthly
• Business: $23/user/mo annually, or $33 monthly
• Scale: $35/user/mo annually, or $47 monthly
• Extra numbers: $5/mo each; US texting registration: $19.50 once plus $1.50–$3/mo
• International calls: add-on credits — check quo.com/rates for your destination

TwinPhone:

• No monthly fee for calling; top-ups from $10
• Calls to US and Canadian numbers: $0.02/min; incoming calls on a rented number: $0.02/min
• Other countries: rate shown before each call
• US or Canadian number: from $3.19/mo

Example — one person, one number, 200 minutes a month to and from US and Canadian phones:

• Quo Starter: $15/mo billed annually, or $19 month to month, with calls included
• TwinPhone: 200 × $0.02 = $4.00 + $3.19 number = $7.19/mo

Example — the same person talking 1,000 minutes a month:

• Quo Starter: still $15–$19/mo
• TwinPhone: 1,000 × $0.02 = $20.00 + $3.19 = $23.19/mo

So the crossover is real: for a heavy North American caller, Quo's unlimited plan is the better deal. TwinPhone comes out ahead for light or irregular use, and for anyone who mainly calls other countries and does not want a seat fee on top.

• Small businesses with two or more people answering customers. Shared numbers and a team inbox are the core of Quo, and TwinPhone has nothing comparable.
• Anyone who needs to send texts. Appointment reminders, quotes, replies to customers: Quo sends SMS; TwinPhone only receives.
• Businesses keeping an existing number. Quo ports numbers on every plan.
• Heavy callers within the US and Canada. Unlimited North American calling on a flat seat price beats paying per minute once you talk for many hours a month.

• Individuals outside North America who want a US or Canadian number to receive calls and texts from US and Canadian senders, without a business plan.
• People who mostly call abroad. TwinPhone reaches 145+ countries from one prepaid balance and shows each rate before the call; on Quo, international calling is an add-on to the seat price.
• Light or occasional callers. With no subscription, a quiet month costs only the number (or nothing, if you do not keep one).
• Anyone who wants to call from a browser tab without installing anything — though TwinPhone also has iOS and Android apps.

If you need to text customers or share a line with a team, choose Quo. If you need a personal line and pay-as-you-go calls, choose TwinPhone.
